A rack server, also called a rack-mounted server, is a device dedicated to use as a server and designed to be installed in a framework called a rack. The rack contains multiple mounting slots called bays, each designed to hold a hardware unit secured with screws. A rack server has a low-profile enclosure, unlike a tower server built into an upright, standalone cabinet. A server rack’s benefits include better rack server space conservation, increased scalability, maximized airflow when used in conjunction with a cooling system, and ease of routine computer maintenance and diagnostics due to the fact that their design makes it simple for technicians and operators to slide rack servers into and out of them.
Dell’s PowerEdge rack servers are designed to address your most challenging workloads, working autonomously and collaboratively across all your IT environments. Paired with our OpenManage integrated IT management system, PowerEdge rack servers include our most powerful automation and reporting features, freeing you to focus on growing your business.
